Description
Abstract: The propagation direction is one of the key parameter of an air shower. Many of current techniques are based on arrival time of an air shower. In this study we introduce a new and completely different approach to determine the propagation direction (and as a result the arrival direction) of an air shower based on filtered peak radio amplitudes which can shape radio signal patterns. For this purpose, a series of simulations have been done with CORSIKA and CoREAS. Simulated air showers initiate from Proton and Iron primary particles with 10^17 eV initial energy and different zenith angles from vertical to 60°. Time based results are converted and analyzed using a specifically designed computer code to calculate the peak radio amplitudes of different electric field components (North, West and Vertical) in the 32-64 MHz frequency band. We investigate eight different shower propagation directions including North-South and East-West orientations in this paper. It is found that by investigating and comparing the orientations of the radio signal patterns from different electric fields components especially the North and Vertical ones, we’ll be able to conclude an air shower propagation direction accurately. This new technique is especially useful for inclined air showers where the impact of an air shower propagation direction is very prominent on its radio signal patterns.
